have made application for Letters Patent in Netherlands on February 22, 1921, No. 18,

117, and for which I have obtained the following patents: German Patent 312,196, llovember 26, 1914; Austrian Patent.78 ,215, September 3, 1917 British Patent 147,097,

July 7, 1920; French Patent 520,098, July 9,

1920), of which the following is a specification. I

My invention relates to modifications and improvements of the objectof Patent No. 1,340,990 granted to Carl Still and Carl iVessel for a coke oven plant, and is sinnlarly to the said invention of the purpose to remove from a stationary colre quenching bench and to load into wagons or the like stored masses of coke in coherent piles, at the same time the coke being screened in a convenient manner.

The essential feature of my invention consists in the combination, with a substantially horizontal bench for quenching and storing coke discharged from coke ovens, of a car travelling along the out-side of said bench and bearing means for scraping off coke masses from the bench and screening them while being loaded into wagons or cars, all as hereinafter described and claimed in the annexed claims.

For the purpose of explaining the inven tion one embodiment of the same is illustrated in the accompanping drawing, in which- Fig. 1 is an elevational section of the apparatus along the line A B of Fig. 2, and

F 2 is a plane view showing a part of the bench along which the coke loading ca-r travels.

in front of the battery of coke ovens 7c is arranged the quenching bench Z of usual construction, namely a large, substantially horizontal platform on which the coke is quenched and stored after it has been dis charged from the ovens; h represents such a heap of coke. @n the side removed from the ovens in there is achannel m, covered with a sieve to carry away the superfluous quenching water, and at a short distance from the channehthe surface of the quenching bench ends in the edge 2. Along this edge,- at the outside of the quenching bench, the coke loading car 0, travels, for example on mile 9 parallel to the longitudinal direction of the bench, so that it can be brought to any desired position along the length of the. bench, where there happens'to be a quenched heap of coke I72, ready for loading; On a second set of rails 5/ parallel to the rails c travels the wagon w, which serves to transport the loaded. coke. The travelling loading car a, in the form shown in the drawings, is also constructed asa wagon consisting of an iron framing c and a box or bunker 7 provided therein. v'lhe-lowerpartof thexbox 7 con-, tains an arrangement for easily emptying the contents, consistingof the flaps p and the chutes a. The framing 6 has at top a practically horizontal frame which consists of two transverse girders q and several longitudinalv girders arranged between them. Between the girders q is a screen extending over the whole area of the bunker and composed of a substantially horizontal piece '1" and an inclined piece 9, directly attachedthereto. The plane of the piece 1 whlch forms the continuation of the surface of the quenching bench Z, and the plane of the piece 1' meet in an obtuse angle along the line At the lower end of the screen plane r is attached a loading chute c, which serves to guide the coke into the wagon to. The screen bars/ s (see Fig. 2) which. are arranged at right angles to the longitudinal direction of the quenching bench, preferably taper in plan, the wider ends being turned towards the oven battery Z: and the narrower ends towards the chute o. In this manner the spaces between the bars gradually increase in width from their beginning at the edge a of the quenching bench to the discharge side of the car 0;; On the extended ends of the girders q are arranged bearings 13 for a shaft (Z, on which two winding drums z, are fixed. The shaft is driven through gearing n (Fig. 2) by a motor m, which may also drive the whole car on the rails 9. When the shaft is driven, the winding drums twind up two ropes b which are attached to a beam 0 actlng as a scraper or sweeper; thus the latter is pulled over the surface of the quenching bench Z and of the screen plane 1'. The apparatus is used by first bringing th car a along the rails g to that place where there is a heap h of quenched coke which is loaded; a wagon w for receiving the cokev driving theshaft d the scraper is pulled towards the wagon and moves the coke heap h as a whole in a coherent pile, first across the quenching bench Z and then over the first piece a" of the screen. Whilst the heap of coke is passing over the screen 1, the

coke ash," which always collects atthe bottom of the mass, and the greater part of the small coke separate and fall into the bunker f. I Therest of the small coke remaining in the heap is removed as the advancing mass ofcoke passes over the edgeg and spreads over'the adjacent inclined piece r -of the screen so thatnow the small coke contained in the upper part of the heap of coke is free to fall on to the screen r and can pass through into the bunker f. The separation of the small coke, as the heap passes over the screen, is'facilitated by the form of the spaces between the bars, the width of 'which continually increases in the direction of movement of the coke, because the sticking of pieces of'coke between the bars and thereby the choking of the'screen vis prevented, since these pieces which partially project through the spaces are drawn forwards until they arrive at a sufliciently wide part of the space between the bars'to fallthrough; The coke having been thus freed from all the small particles, falls over the chute 1; directly into the wagon to and is ready for dispatch. When the heap of coke h in being moved over the screen of the car a has been advanced so far that the scraper 0. has reached the screen plane 1" and isv resting upon it; then the car a; together with mass of coke brought on may be displaced from its first position along the bench Z at will, whereupon this coke can also be loaded in any other wagons positioned.

in some distance. from the aforesaid wagon a. After the whole coke heap taken off by the scraper c has been loaded into wagons, the travelling car acan be moved to another part. of the coke quenching bench Zto carry out the same work and so on, until finally the bunker f is ,filled with small coke and ashes andmust be emptied. This is doneat a pointy on the track intended therefor by opening the flaps p and discharging the conents over'the chutes a, whereupon the ap- 'paratus is again ready for use.

The advantages of the invention are considerable and manifold. The troublesome and expensive work of loading quenched coke by manual labour is substituted by mechanical means which perform the operation in a very short time; with modern coke ovens of'considerable output, this is of im-' portance. 7 charged from a plurality OfCOkG ovens can be stored on the bench after quenching as required and removed and-loaded in any succession at will, quite independently from the operation of the single coke ovens. The

The several heaps of coke disapparatus itself is simple and can be made f without high costs, and, what is of considerable advantage, it can be applied to existing coke quenching benches of ordinary construction without difficultyand special provision. The coke thus loaded is suiiiciently cleaned in the'simplest manner from small coke,. which is not possible with manual treatment; moreover, there is combined with the immediate loading up of the larger coke, 1

the simultaneous collection of the small coke, in such a manner that even this part of the coke can be supplied to anyparticular place of use without difi'iculty.
